Donald and Daisy in their Kermit and Piggy costumes on the cover of Micky Maus Magazin.

Donald Duck is a popular Disney cartoon character who debuted as a supporting player in the 1934 short The Wise Little Hen. The duck soon rose to become the studio's major star, eclipsing Mickey Mouse, in more than 100 theatrical cartoons through 1961. The short-tempered, incomprehensible quacker was also a major star in comics (gathering an equally popular array of co-stars such as his nephews Huey, Dewey and Louie and uncle Scrooge McDuck), made occasional appearances on radio, and has remained an active figure in Disney television shows, comic books, and countless shows and parades at Disneyland and Walt Disney World.

Unlike Mickey, Donald has yet to interact directly with Kermit or any of the other Muppets. However, he has been referenced many times over the years. He also dressed as Kermit on the cover of an issue of Micky Maus Magazin along with his girlfriend Daisy Duck, dressed as Miss Piggy.
